Eh no it is not applied, was just looking at the series locally and I guess it got added to the b4 ty pile. I am, however, wondering if we'll see a v6 of this soon? I had some comments on the nvme dma mapping, that can be improved, but I'd rather defer that to post getting this included. If the series is dormant, just let us know, and we can pick up the bits and pieces. -- Jens Axboe
